The er'nlomiinflentv shown in Fig. y1 comprisesAV a. heel pull member having its front part formed byva ilexible lamina 2'6.y The front end lofplemfiina fafplfovides two, hinges Se with the toe guide1 cheeksl 2 and therear endjforrmsa yokeyZl to which on'either sideof ski l are secured cables 3 which constitute together with a heelrspring 4 and atightenerv the rear, part` of the heelpull member. This laminax26 .can rollktoget'her.withV the` boot sole on the top `face of skiV l` andc'an be lol'el down to the ski by means of a pair ofV switching latches 2,8,.which are adapted to engage the rear end or yoke 21 of lamina 125.. A `iront lever 29 having a somewhat cranliedfshaft 30, as shown in Fig. 1, which is connected via a push rod3i with swinging latches 28 vserves to Voperate thelatter. When lamina 26together with yoke 21 aredepressed on skill and lever 29 is turned,

forward, latchesn will loclelamina 275, thus lenvabling the heel` pullmember` to exert aA diagonal tension'upon the heelV of 4the boot, Vwithoutfii')'ber-V ing necessary to Vopenthe binding beforehand. In order to secure lever 23 against imintensionaly actuations the moving parts of thelocking device may be assembled, sufficient friction.

Cables 3`together with heelspring` 4 and tightener are securedto yoke ,38 toconstitute the rear portion ofltheheel pull member. When tighteneru' is closed, lamina i8 will be withdrawnl sofar'tliatV stops Y5I 4providedthereon will Vbe apes, plied against tongues 'dwhereby lever i9,takes 3 the position shown in dotted lines. Besides, yoke 38 is provided with eyes 39 as in the preceding example, which may engage in hooks 40 screwed to ski l, when yoke 38 is depressed on the ski by boot sole l and simultaneously lever 49 will be rocked into the position shown in full lines, under elongation of heel spring 4. Thus heel Illa is placed under diagonal tension. Lamina ll may extend further backward, for instance Y below heel la.

Fig. 4 shows a modification of the manipulating device which comprises a tightening lever 56 having an axle 51 provided to be turnably seated in either of two pairs of bearings 59 and 50 of a support 58 which is U-shaped in cross section and is mounted on ski I in front of cheeks 2. Cables 3 of the heel pull member are connected with tigthening lever 56. The bearings 59 and 60 in each sidewall of support 53 communicate with each other through a guide slit El having the shape of an upwardly bent knee. A lever 62 engages with its one arm the axle 51 of lever 56 from below, whereby when the other arm of lever 62 is depressed, axle 51 will be lifted off bearings 59 along slit 6l up to the knee thereof and by the action of heel spring 4 it will be pulled from there along the remaining part of slit 6| into bearings 60. When tightener 56 is depressed with its axle 51 in the front bearings 59, a diagonal tension upon heel Illa will be obtained by the engagement of yoke 38 in the hooks 40. When tightener 56 is depressed with its axle 51 in the rear bearings 60, the binding is closed under normal tension in the heel pull member and, when tightener 56 is swivelled up, the binding is open.

In Fig. 4 the compression spring 53 may be omitted and the desired change of length in the heel pull member can be performed exclusively by the elasticity of heel spring 4.

It is obvious that still further changes and modifications may be made in the details of construction and design of the above described embodiments of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
